Abstract: A monitoring system for remotely monitoring a state of pole-mounted equipment in a power distribution or transmission grid is provided. The pole-mounted equipment includes an indicator device configured to present state information indicative of a state of the pole-mounted equipment. The monitoring system includes a status monitoring device movable via a drive or propulsion system. The status monitoring device is configured to obtain the state information from the indicator device when located within a communication range of the indicator device.

Abstract: Disclosed is a leakage current measuring device for a grid protection system protecting a power distribution or transmission grid from damage in case of a power surge, the grid protection system including a disconnector device and a surge arrester connected in series along a grounding path, the grounding path connecting a phase of a power distribution or transmission grid through the surge arrester and the disconnector device to ground, the disconnector device being configured for being activated in case of an overload condition, thereby disconnecting the surge arrester. The leakage current measuring device includes a leakage current sensor for measuring a leakage current IL flowing along the grounding path, the leakage current IL being indicative of the electrical connection status of the disconnector device. The electrical connection status is one of an activated and an inactivated status of the disconnector device.

Abstract: A device, a method and a system for monitoring an electrical connection status of a disconnector device (110). The disconnector device (110) being connectable to pole-mounted equipment in a power distribution or transmission grid (200), thereby disconnecting the pole-mounted equipment. The connection status monitoring device (100) comprises a determining section (130) configured to determine whether the disconnector device (110) has been activated and to generate connection status indicator data, indicative of whether the disconnector device (100, 110) has been activated. The determining section (130) further comprises a wireless communication section (140) which is adapted to connect to a wireless communication infrastructure (150) using a wireless communication protocol, and to transmit the connection status indicator data over the wireless communication infrastructure (150).
